After analyzing 15 different sets of Monkey Rocker plans, the single most common failure is the seat angle. Most draftsmen copy the seat of a dining chair (90-100 degrees back angle). For a low rocker where your feet are on the ground, a 90-degree back forces your pelvis into a posterior tilt, causing lower back pain in 20 minutes.

This is a generalized overview of the mechanism found in mechanical rocker plans. You will need specific CAD drawings or cut lists for exact dimensions.
